the online save game feature should be be there for all games , rather than the local save option, by which i can play the game from any computer... if not for all games, then at least an option/tag by which we can know which games have this feature..
That particular feature is used only for those games which are made in direct cooperation with AG, or is under AG sponsorship. That makes them rather exclusive.
It would be nice if there was a universal save option... Something of that effect might show up eventually.
